With so many 3d printers and open source build plans out there it can sometimes be challenging to make the final decision. Now days there are so many options to choose from.
- DIY Kits
- Design and Build Plans
- Plug and Play (ready out of the box)
- Upcoming Projects to soon be released
What To Look For In a CoreXY Design
When you think about a good machine build you have to consider a few things. How developed is the design? Many common designs will have:
- Contributors designing fixes, mods and other spun off remixes.
- How many mods are there that could allow you to modify your printer for custom applications
- Is there a user group that you use as a resource to troubleshoot or upgrade and update your build. While there are many resources to draw upon User groups will keep you in the circle of news, updates and creative solutions.
CoreXY DIY Designs & Kits
- Voron 3D Printer
- BLV MGN Cube
- E3D ToolChanger
The Voron V2 by Voron Design is a well engineered printer that looks very promising. It has a great community that loves their builds and very well documented.
- Build volume: Scalable
- Extruder: AfterBurner
- Enclosure: Open or Enclosed
- Moving Gantry
- Electronics: Duet3D / Klipper
The Voron V2 motion system is a corexy moving gantry that utilizes four point z-axis belts. It’s a light weight and high speed printer that prints beautiful parts. The machine has precision linear rails for the X- and Y-axes and a dual-drive extruder. learn more
Jubilee is probably the next biggest project. If your looking for a highly customizable printer you’ll have to take a look at this. It’s a multi-tool motion platform that has made much progress in the last year. Out-of-the-box, Jubilee is configured for multimaterial 3D printing compatable with current E3D toolchanger parts. Jubilee is meant to be extended by the community through custom tools and applications.
- Modular Platform
Although the Jubilee is new a few manufactures have recently started offering all-metal upgrades for the platform. 713Maker sells a Custom cast aluminum magnetic heated bed and Mandala Rose Works sells a lightweight machined aluminum crossbar similar to the E3D Toolchanger crossbar. learn more
BlackBox – Multitool 3D Printer
A very interesting project created by Marc Schomann that aims to build a flexible platform for multitool fabrication. Think of it as a multitool / multimaterial manufacturing platform for printing soft robots, highly integrated assemblies or even living tissue.
- 300mm x 300mm x 240mm Build Area
- Interchangable Printheads
BLV MGN Cube
The BLV MGN Cube is an elegant diy corexy design that uses MGN12h linear rails to have a high quality and reliable printer. Created by Ben Levi, this open source project is a reliable, modular and easy to build design keeps a balance of usability and economical. It has an open ended and accessable frame and has a 300mm x 300mm build area.
- Well Documented
- Economical and Available Parts
- Fine Tuned Slicer Profiles
The BLV MGN is probably one of the most documented printers on the internet.learn more
The SecKit 3d printers is known for it’s designed for rigidity, speed, low noise, upgradeability and all-metal parts….. beautiful machined all-metal parts. It’s an all-metal linear rail CoreXY 3D printer kit designed for rigidity, multi-material and easy maintenance. The SK-Go² is the current model offered. It has a small community of users but they all seem to be very hapy with their machine. learn more
- All Metal Parts
- XYZ-Linear Rails (HIWIN or non-HIWIN)
- 3-point bed leveling
The HeVort is a design based off the Hevo and it has a new triple z-axis motor self levelling print bed that’s out this word. If you haven’t seen it, you have to watch the video below.
Next let’s look at the Railcore design. Developed by J. Steve White & Tony Akens of RailCore Labs and produced by Project R3D. This core xy design has some kick. Although this a new open source build has a strong and active community. It is a well thought out design that has verity of CNC machined upgrades to pimp your printer. The prints that are made from the machine are absolutely beautiful. This 3d printer build is most commonly found using the Duet Wifi to power the system. The print quality is spectacular with it’s high precision 0.9 degree steppers. The pros of the Railcore corexy is:
- Linear Rails on X,Y and Z-axis
- 15mm extrusions to reduce the price of BOM
- CNC machined upgrade parts
- Space & Cost efficient
- Flexibility and scalabiltiy in the design
The Railcore 3d printer’s ecosystem of parts also include a variety of CNC machined aluminum parts that can be found by 713Maker and Mandala Rose Works that can make your printer look like a hotrod.
If you havn’t seen the E3D ToolChanger motion system , you’re missing out. The open source design is most likely the future of 3d printing… or at least the begining of true desktop manufacturing. While the motion system is somewhat in beta testing phase the new platform has a lot to promise and has inspired a wave of new printers exploring different tool changing methods.
CroXY Crossed Gantry 3D Printer
Designed and built by Wes Cherry
CroXY is a fully enclosed 3D Quadrap printer with a crossed linear rail gantry design, direct drive extruder and a kinematically mounted bed that moves in Z with three ball screws. Although this printer isn’t exactly a corexy it does utilize the same kinematics.
What Is A Quadrap Motion System?
The quadrap mechanism is similar to a corexy but one or two extra stepper motors. It’s a cross between a core-xy and the ultimaker’s XY mechanical arrangement.
- X- Axis
- X2-Axis or Y2-Axis / Both X2 abd Y2-Axis
The crossed members at the print head carriage allow low moving masses because none of the motors (X,Y or E) are moving with the extruder carriage. The corexy’s belt stretch issue is minimized when scaled up but resistance may increase.
- Minimized belt length
- Increased Resistance
